DETAILED DESCRIPTION

[0025] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Reference Figure 1-Figure 3 A warp knitting machine yarn frame with adjustable yarn bobbin angle, comprising a base plate 1, an adjusting mechanism 2 and an auxiliary control mechanism 3; a vertical plate 11 is provided on the base plate 1; the adjusting mechanism 2 comprises a mounting seat 21 and a rotary drive assembly 22, the mounting seat 21 is rotatably arranged on the vertical plate 11, and the mounting seat 21 is connected to the vertical plate 11 through a torsion spring, and a yarn bobbin 211 is rotatably arranged on the mounting seat 21; the rotary drive assembly 22 is arranged on the vertical plate 11; the auxiliary control mechanism 3 comprises a connecting assembly 31, a control assembly 32 and a transmission assembly 33, the rotary drive assembly 22 is transmission-connected to the connecting assembly 31, the control assembly 32 is used to control the connection and disconnection of the connecting assembly 31, and the two ends of the transmission assembly 33 are transmission-connected to the connecting assembly 31 and the mounting seat 21 respectively.

[0027] The utility model realizes the function of adjusting the angle of the yarn drum 211 through the bottom plate 1, the vertical plate 11, the adjustment mechanism 2 and the auxiliary control mechanism 3, and through the setting of the auxiliary control mechanism 3, it can switch between the manual adjustment mode and the automatic adjustment mode. During the working process, the manual adjustment mode can be used to adjust the designated yarn drum 211 individually. When the automatic adjustment mode is used, the mounting seat 21 is reset under the elastic force of the torsion spring, and when subjected to external force, it can automatically deflect in the corresponding direction to avoid damage due to abnormal yarn tension, thereby solving the problem that the traditional warp knitting machine cannot adjust the designated yarn drum 211 individually. In the working state, when the designated yarn drum 211 needs to be adjusted, the operator adjusts the state of the connecting component 31 through the control component 32, and then connects the transmission component 33 and the rotating drive component 22 through the connecting component 31, and then drives the mounting seat 21 to rotate through the rotating drive component 22 to adjust the angle of the mounting seat 21. When there is no need to adjust the angle of the designated yarn tube 211, the operator disconnects the connection component 31 through the control component 32. At this time, the mounting seat 21 is in the middle position due to the elastic force of the torsion spring. In the subsequent working process, the mounting seat 21 deflects itself under the tension of the yarn, thereby preventing the yarn from being subjected to excessive friction or being damaged due to abnormal tension.

[0029] The utility model realizes the function of connecting the rotary drive assembly 22 and the transmission assembly 33 through the connecting ring 311 and the docking ring 312. The docking ring 312 is provided with a docking post 3121 and a first elastic member 3122. The docking post 3121 is slidably mounted on the docking ring 312. The two ends of the first elastic member 3122 are respectively connected to the docking post 3121 and the docking ring 312. The connecting ring 311 is provided with a docking groove 3111 that matches the docking post 3121. When adjusting the designated bobbin 211, the operator controls the docking ring 312 to move toward the connecting ring 311 through the control assembly 32 until the docking ring 312 abuts against the connecting ring 311. Then, the operator drives the docking ring 312 to rotate through the rotary drive assembly 22. As the docking ring 312 rotates, when the docking post 3121 is aligned with the docking groove 3111 on the connecting ring 311, the docking post 3121 is plugged and matched with the docking groove 3111 under the elastic force of the first elastic member 3122. The docking ring 312 drives the connecting ring 311 to rotate synchronously, and the connecting ring 311 drives the mounting seat 21 to rotate through the transmission assembly 33, thereby realizing the connection between the rotation driving assembly 22 and the transmission assembly 33.

[0031] The utility model realizes the function of controlling the lifting and lowering of the docking ring 312 through the connecting frame 321, the column 322 and the linear driver 323. The linear driver 323 is preferably an electric push rod, and the linear driver 323 is electrically connected to the controller; when it is necessary to control the designated mounting seat 21, the operator pushes the connecting frame 321 to move through the push plate 3211, and when the docking ring 312 abuts against the connecting ring 311, the elastic protrusion 3222 on the column 322 is plugged into the through hole on the push plate 3211, and the push plate 3211 and the connecting frame 321 are supported by the elastic protrusion 3222. When it is necessary to adjust the state of multiple mounting seats 21 at the same time, the controller sends a signal to the linear driver 323, and the linear driver 323 drives the column 322 to move up after receiving the signal, and the column 322 drives multiple support plates 3221 to move, and the multiple connecting frames 321 are pushed up by the multiple support plates 3221 at the same time, so that multiple connecting components 31 are all in a connected state. If the connecting frame 321 is originally in an upward state, after the column 322 moves upward as a whole, the elastic protrusion 3222 separates from the through hole on the push plate 3211. When the linear driver 323 controls the column 322 to reset, the connecting frame 321 moves downward under the action of gravity when it is not supported, and then resets itself.
